Lexile-to-Grade Correspondence Charts
There is no direct correspondence between a specific Lexile measure and a specific grade level. Within any classroom or grade, there will be a range of readers and a range of reading materials. For example, in a fifth-grade classroom there will be some readers who are ahead of the typical reader (about 250L above) and some readers who are behind the typical reader (about 250L below). To say that some books are "just right" for fifth graders assumes that all fifth graders are reading at the same level.
The Lexile® Framework for Reading is intended to match readers with texts at whatever level the reader is reading.
